Mining Explosions in the Khibiny Massif (Kola Peninsula of Russia) Recorded at the Apatity Three-Component Station
Abstract
This report offers a description of the three-component seismic station that was installed in Apatity on the Kola Peninsula of Russia in June of 1991. Data from this station are useful for studying mining explosions in the nearby Khibiny Massif. Colleagues at the Kola Regional Seismological Center in Apatity have provided us with detailed information on 200 mining explosions undertaken during June 1991-September 1992 and we have compiled a data base comprising data from 61 of these explosions. The data are used to estimate the noise level at Apatity station and also for estimation of P-wave arrival azimuths, using a broad band slowness analysis technique. Values for the true azimuths are available from the information presented in this report and the azimuth residuals are found to have a median value of -7.06 degrees. A small- aperture array was installed close to Apatity in the fall of 1992 and some perspectives for the future use of data from Apatity are discussed.
